Origins of “Cost an arm and a leg”
“Cost an arm and a leg” originated in America, sometime around the Second World War. One of the earliest citations is from 1949 in The Long Beach Independent. The quote, which is used in reference to coking an affordable Christmas meal, reads:
Food Editor Beulah Karney has more than 10 ideas for the homemaker who wants to say “Merry Christmas” and not have it cost her an arm and a leg.
Here, the speaker is describing one person seeking out recipes that aren’t going to cost “an arm and a leg,” or a lot of money. Some related phrases that use body parts as a means of sacrifice for something one longs for, might be connected to the coinage of this phrase. For example, this quote from Sharpe’s London Journal. It reads:
He felt as if he could gladly give his right arm to be cut off if it would make him, at once, old enough to go and earn money instead of Lizzy.
These lines were published in 1849, but examples of this kind of hyperbole are found in earlier publications as well. Another example, from several decades later, reads:
A man who owes five years subscription to the Gazette is trying to stop his paper without paying up, and the editor is going to grab that back pay if it takes a leg.
While these two quotes don’t use “an arm and a leg,” it’s easy to see how they’re related and how the phrase might’ve evolved naturally from them. Lovers of language will also be able to find versions of this phrase in other languages as well, such as French and German.
Interestingly, “an arm and a leg” has another compelling, but baseless, explanation. Some believe the phrase originated in painting commissions in which artists are described as charging more for portraits that included body parts. But, there is no evidence for this theory.
